Tom Riddle, DVM, renowned authority on equine reproduction and the retired co-founder of Rood & Riddle Equine Hospital in Lexington, Kentucky, received the 2024 Distinguished Educator–Mentor Award from the American Association of Equine Practitioners (AAEP).

The Distinguished Educator–Mentor Award honors an individual who by her or his actions and commitment has demonstrated a significant impact on the development and training of equine practitioners through mentoring. Riddle received his award Dec. 10 during the President’s Luncheon at the AAEP’s 70th Annual Convention, in Orlando, Florida.

After receiving his veterinary degree from the University of Georgia in 1978, Riddle spent four years at Spendthrift Farm, in Lexington, Kentucky, before joining Bill Rood, DVM, in his ambulatory practice to form Rood & Riddle in 1982. Three years later the pair broke ground on their landmark hospital, and the practice has grown exponentially since. 

Through his dedication to teaching and mentoring, Riddle has profoundly influenced and helped shape the careers of veterinary interns and others who have come through the practice. As a result of his guidance, many of Riddle’s interns went on to complete theriogenology (the study of animal reproduction) residencies, attain board certification, and ultimately become influential mentors themselves. 

“The consequence of Dr. Riddle’s mentorship has had a trickle-down effect,” said co-nominator Virginia Reed, DVM, “creating generations of skilled, enthusiastic equine veterinarians ready and willing to mentor other veterinarians throughout their careers.”

In addition, Riddle has spearheaded immersive continuing-education events on equine reproduction, including a low-cost symposium where theriogenology residents gain hands-on skills with guidance from established theriogenologists. 

“Dr. Riddle’s guidance and support have shaped the careers of so many veterinarians,” added co-nominator Meghan Connor, DVM. “His ability to provide leadership while allowing the personal and professional growth of his mentee is unmatched. His upstanding morals and dedication to honesty instilled great ethics that have stayed with me into many aspects of veterinary practice.”
